1) Israel Systematically Violates the Human Rights of Palestinians in the Occupied Territories
2) US Aid Violates US Law. Laws passed by Congress prohibit the president from furnishing military aid or selling weapons to any country that consistently violates internationally recognized human rights standards.
3) Israel systematically discriminates against Arabs, Palestinians and non-Jews. Effectively, Israel is the Apartheid state. We should not support that without at least some conditions.
